Title
of talk: "Pervasive Streaming
Media and Computer Graphics"
Abstract:
Where does computer graphics fit into the world of streaming
media
and wireless gadgets? Digital audio is now pervasive with
filE formats like MP3 and its associated handheld devices.
Computer games titles for wireless and mobile devices are
beginning to appear. Online advertisers and instructional
designers are realizing the importance of building content
that can be accessed and displayed on personal digital assistants.
The Synchronized Multimedia Integration Language (SMIL) facilitates
combining audio, video, text and image files into one streaming
media presentation. But where does computer graphics, specifically
interactive 3D applications, fit into this picture? Is there
a need for rendering computer graphics imagery on handheld
devices and mobile phones? Maybe a language of minimal graphics
is all that is required?
This
talk will visualize and ask more questions about emerging
trends and technologies associated with pervasive streaming
media and computer graphics.

Theresa-Marie Rhyne is a multimedia and visualization
expert in Learning Technology Service at North
Carolina State University. She is responsible for architecting
the overall approach to the campus-wide support of streaming
media technologies for online instructional learning. In addition,
she is a practicing fine artist in the mediums of collage
and computer graphics and exhibits her work internationally.
From
1990 - 2000, she was a government contractor (initially for
Unisys Corporation (1990
- 1992) and then for Lockheed
Martin Technical Services (1993 - 2000)) at the US
EPA Scientific Visualization Center. She was the founding
visualization expert at the Center.
She was
the Panels Chair for SIGGRAPH
1996 and served as a Director-at-Large on ACM SIGGRAPH's Executive
Committee from 1996 - 2000. She was the Lead Conference Co-Chair
for IEEE
Visualization 1998 and the Past Conference Co-Chair for
IEEE
Visualization 1999. Recently, she served as the Eurographics
2001 International Programme/Papers Co-Chair.

"Beyond Soft Objects"
(The Jungle BlobTree Software Project)
Abstract:Automatic
blending has characterized the major advantage of implicit
surface modeling systems. The introduction of deformations
based on space warping and boolean operations between primitives
has increased the sefulness of such systems. In this work
a further enhancement is proposed that will increase the
range of models that can be easily and intuitively defined
with a skeletal implicit surface system. A hierarchical
method is described, which allows arbitrary compositions
of models using warping and boolean operations.
We call this structure the BlobTree.
Blending and space warping are created in the same way as
union, difference and intersection, i.e. as nodes in the
BlobTree. Some examples are presented of interesting models
which can be built easily using our approach that would
be very difficult to represent with conventional systems.
Recent work involves adding animation tracks, local refinement
methods, 2D texturing and precise contact modelling. A Python
interface has been built to the modelling and animation
system, some examples will be shown and the system will
be made available for demonstrations.

of Bradford and subsequently worked as a Post-Doc at the
Royal College of Art in
London.
In the late 1970's he worked on sequences for the movie, Alien.
Brian emigrated to Canada in 1981 and has been working at
the University of Calgary

modelling and animation since the mid-1980's, a project which
he started with brother Geoff
Wyvill (University
